The hot lava was bubbling up, and the giant red tower was shrouded in blinding light, with red symbols flashing, like an ancient god tower, which had been in the area for hundreds of billions of years.

Fusu's eyes narrowed into slits and he looked closely, this was a huge tower that was extremely terrifying.

This place should be in the center of the Clear Void Cave Heaven, where magma is like a sea, everywhere, and there is no end. And that magnificent tower, right in the center of the magma sea, was up and down, extremely tall, and flowing with runic light in the sky.

"There is indeed a kind of divine fire in this, and it is also an extremely high-ranking Haoran Saint Yiyan," Fusu muttered to himself, it stands to reason that if there is a divine fire in this place, then after getting close to a certain distance, his heart fire must be able to sense it, but until this time, his heart fire will not react.

In fact, the moment he saw the Flame Ox, he had a guess in his heart, but at that time he felt that the possibility of divine fire in it was very small, and later after encountering those magma lakes, he felt more and more that he had not guessed wrong, and now he was 100% sure that there must be divine fire here, but it was covered up by people with great magical powers.

"Hehe, it seems that Xiaoyou is also well-informed! even Haoran Shengyiyan knows," a voice came from the giant tower, as if he heard what Fusu said.

"This cave is full of such pure Haoran righteousness, it is really difficult to imagine that there will be a demon beast like the flaming cow here, and the cave occupied by Confucianism is called Qingxu Dongtian, if my guess is right, this cave must be from outside the sky, if this is the case, then according to the records in the ancient books, there can be no Haoran righteousness in this, at the beginning, I thought that the Haoran righteousness in this may be related to the founder of Confucianism, Or there must be some great Haoran righteous qi magic weapon in this cave, after all, these Haoran righteous qi are not like the spiritual energy between heaven and earth that comes from the spiritual veins, and they cannot be born out of thin air, when I saw the Flame Ox, so I had such a small guess," Fusu said lightly;

"It's not easy for little friends,"

"Seniors should know Sage Kong, right?" Fusu went straight to the point and asked the doubts in his heart, and although the voice coming from the giant tower was immature, Fusu would not think that it was a newborn child, it was definitely an old monster who had lived for an unknown number of years, and it was also a terrifying old monster.

There was no sound from the giant tower for a long time, but there were more runes in the void, flashing with divine light, and if you felt it carefully, you could find that one step after another was horizontally formed in the air, circulating mysterious energy fluctuations.

Fusu glanced up, was stunned for a moment, and then thought about it, then jumped up, stepped on the stairs and went straight to the giant tower, but the moment he stepped on the stairs, Fusu's heart shook, the space laws here are amazing, if there are no these ladders, it is impossible for the cultivation of the peak of the fairy realm to fly for a thousand years, or ten thousand years, and it is impossible to reach the giant tower, and the distance between the two stairs is tens of thousands of miles.

Fusu glanced around, took a quick step, stepped on the ancient steps, and below was the tumbling magma, the temperature was frighteningly high, and he ran for more than half an hour before he came to the giant tower, and the two gates of the giant tower closed, blocking the way.

Under the red giant tower, Fusu paused, he raised his head to look at this giant tower filled with ancient and vicissitudes of life, the years have left mottled lines and traces on it, it seems to have existed before the opening of the world, and the eternal and ancient stand still.

But what is surprising is that with a gentle push from Fusu, the gate of the ancient tower is wide open, this door is not as difficult to open as imagined, and it can be easily entered, thinking that the people in the ancient tower did it intentionally.

Fusu looked up, the inside was hazy, like a fairyland, very grand, and there was no end in sight, as if the inside and outside of the door were two different worlds.

However, Fusu suddenly stopped moving forward, subconsciously stepped back, and showed a solemn look on his face, the door can be easily pushed open, it does not mean that it can be easily entered, and the appearance of those fire bulls before was just a test given by the people in the tower or wanted to see the power of the heart fire.

And his intuition told him that life and death were in this step, and he couldn't be careless.

Fusu frowned, closed his eyes, and began to use the power of the heart fire to feel if the door would be arranged by other means.

Ten minutes later, Fu Su opened his eyes, a little disappointed, he didn't find anything, for such a result, there are only two possibilities, one is that his cultivation is too low, his heart fire is still very weak, and the means arranged here are not what he can spy on now, and the other is that there are no means arranged in this place at all, but he feels that the former is the most likely and the latter is negligible.

"This tower is called the Holy Emperor Tower, if you want to enter, you need to go through the test, the first test, when you step into the gate, you will be transported to a thunder pool, if you can survive nine hours in it, you can enter the first layer, of course, the power of this thunder pool is also set according to the strength of cultivation," just when Fusu hesitated, a childish voice came.

"Little friend, don't be in a hurry to refuse, through the test, you will get a chance, you may not look down on ordinary opportunities, but I promise that this opportunity will have a great effect on you, at least it can solve the problem of the coexistence of the two wisps of extreme cathode and yang essence in your body," the immature voice added;

Fusu was immediately stunned for a moment, and his face showed joy, but he quickly calmed down and said, "If ordinary people come, the seniors may not be willing to open this door, right?"

"If the seniors want to make any deal with me, please ask the seniors to explain it first, so as not to get the embarrassing scene of taking the benefits of the seniors and making an embarrassing scene that is not easy to refuse," Fusu later added;

"Since Xiaoyou is so refreshing, then I will also say it bluntly, Xiaoyou has also noticed the green evil power in the bodies of those spirit beasts before, it is a very terrible power, a power controlled by an evil alien creature, and under the Holy Emperor Tower, it is convenient to suppress a terrifying alien creature, so I hope that one day Xiaoyou can help me, wipe out this creature, and remove a disaster for the world," said the immature voice;

"How did the seniors recognize the fire in my body?" Fusu did not immediately agree, but asked;

"In an extremely distant era, there was a peerless Tianjiao who ignited the divine flame in his heart, and he also called it the heart fire," said the immature voice lightly;

"What? Someone has ever lit a fire in his heart?" Fusu was stunned and dumbfounded, such a big event was not recorded in ancient books.

"It's just that the good times didn't last long, and that peerless Tianjiao was burned to ashes on the ninth day when he ignited the fire in his heart, and even those supreme giants who stood at the top of the world couldn't save it," said the immature voice;

"You should be the first person in the world who can keep the fire in your body alive and under your control," the voice added, and it was not hard to hear the shock and incredulity in his voice.

"Uh......"

Fusu was stunned again, ignited the fire in his heart, but only lived for nine days, could it be that he was eaten by the fire in his heart?

"The heart fire is nothing to burn, even your own host can't escape the fate of being burned to death, I really don't know how Xiaoyou managed to make the heart fire one with himself and still under your control?"

Fusu directly ignored this question and did not respond, he naturally knew how difficult it was to let Xinhuo become one with him and be under his control, and the price he paid for it was unimaginable.

He pondered for a moment and said, "I can feel the horror of this tower, but I don't know what kind of creature it can't even erase it."

"This is a royal family of alien beings, a very powerful being, and it is too difficult to kill it, so it can only be suppressed," said the immature voice;

Fusu was a little speechless, he knew that it was a foreign creature, but what kind of alien creature was it? But he didn't dwell on this question, but asked, Is the predecessor the instrument spirit of the Holy Emperor Tower? Or the owner of the Holy Emperor Tower?

The immature voice did not hide anything, I am neither the spirit of the Holy Emperor Pagoda, nor the owner of the Holy Emperor Pagoda, this pagoda is the natal thing of my senior brother, and I am the guardian of the pagoda, and at the same time, I am reborn in Nirvana.

Fusu's heart shook, this tower is amazing, there are few gods in the world that can match it, and even the heyday of the imperial sword cannot be compared with it, so you can imagine how powerful the owner of this tower is, and this person calls him a senior brother, so how strong is their master?

And the reason why this person's voice is immature, I think that he should have succeeded in Nirvana.

What is the relationship between the predecessor and the human emperor pen? Fusu asked again, when he entered this cave, he found that there were mysterious runes on the stone door that closed the cave, those runes were very unfathomable, not trivial, and they were definitely not arranged by the Confucian sage, if it was said that it was from the human emperor pen, it was difficult to say, after all, the damaged human emperor pen was born not long ago, and it was probably impossible to arrange such a complicated and mysterious rune, but when Fusu came in, I really didn't expect that there was such a big secret hidden here, so even if he felt a little unreasonable, he could only attribute it to the unusualness of the emperor's pen.

But now that I think about it, I am afraid that there is some secret connection between the human emperor pen and the people in the tower.

"Which broken imperial pen are you talking about?" asked the childish voice;

"Exactly," Fusu responded;
